I do not know either. RFC 3261 is your friend :-)
The branch parameter in the topmost Via header field of the request
is examined. If it is present and begins with the magic cookie
"z9hG4bK", the request was generated by a client transaction
compliant to this specification. Therefore, the branch parameter
will be unique across all transactions sent by that client. The
request matches a transaction if:
1. the branch parameter in the request is equal to the one in the
top Via header field of the request that created the
transaction, and
2. the sent-by value in the top Via of the request is equal to the
one in the request that created the transaction, and
3. the method of the request matches the one that created the
transaction, except for ACK, where the method of the request
that created the transaction is INVITE.
So actually the Via header and CSEq header

klaus
actually transaction matching is based on branch
id in Via header
Entirely?
